Regeneratepkg generates a compatible Slackware package that includes the files
that a given package installs onto your system.
It can be useful if the program has been installed onto your system by pkgtool
(or checkinstall), but you lose the original package and you need to build it
again.

Example:
To generate the 'nmap' package run: regeneratepkg [options] nmap
To list the packages that begin with 'a' run: regeneratepkg [options] a

options: -l, --list - list all installed packages
-d, --date - print installation date near package name
-v --verbose - print progress information
-h, --help - print this message
-V, --version - print version

# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description. Line
# up the first '|' above the ':' following the base package name, and the '|' on
# the right side marks the last column you can put a character in. You must make
# exactly 11 lines for the formatting to be correct. It's also customary to
# leave one space after the ':'.
